The highest percentage of isolation was from layers with percentage of 46.3% while from broilers the percentage was 3.1%. The best sample for detection of Gallibacterium species was internal organs than tracheal swabs with a percentage of 46.9% and 5.9% respectively. The highest rate of isolation from broilers was from El-Fayoum Governorate with a percentage of 12.5%, while El-Dakahlia Governorate showed the highest percentage of isolation in layers with a percentage of 85.7%. The highest rate of isolation from broilers was from Avian breed with a percentage of 9.5% while from layer breeds, the highest percentage was from Shipper breed with a percentage of 80%. By using PCR for detection and typing revealed 8 positive samples out of 23 isolated Gallibacterium species with specific band at 1080 base pair. |
